本发明涉及上肢动作空间范围推算系统的构建方法，所得系统，及该系统的使用方法。该构建方法包括：以受试者作为动作实施者进行上肢动作的模拟运动学实验，通过对其上肢动作的运动捕捉，获得运动学数据；建立全身人体模型；结合人体模型，对运动学数据进行解析处理，计算获得人体节点标记点、刀具或非刀具器械或徒手手部标记点在上肢动作中的三维空间坐标动态变化值；计算上肢动作空间范围指标；建立上肢动作空间范围推算系统。本发明建立的上肢动作空间范围推算系统，能够计算出伤害人上肢动作空间范围指标，帮助刑侦人员研判伤害案件中伤害人动作轨迹与案件现场空间的相容性，为推测案事件演化过程提供科学依据。 The invention relates to a construction method of an upper limb action space range calculation system, the obtained system and a use method of the system. The construction method comprises the following steps: performing a simulated kinematics experiment of upper limb actions by taking a subject as an action executor, and acquiring kinematics data by capturing the upper limb actions of the subject; establishing a whole-body human body model; in combination with a human body model, analyzing and processing the kinematics data, and acquiring three-dimensional space coordinate dynamic change values of the human body node mark points and the tool or non-tool instrument or bare-handed hand mark points in the upper limb action by calc
